From a luscious flower garden to a set of well-maintained planters, beautiful flowers enhance the look of your home, give it appeal, and add color and fragrance. While it is wonderful to enjoy planting and caring for attractive annuals and perennials, the experience can become more rewarding when you sow your own flower seeds. While the basics of how to sow flower seeds are simple, the task of caring for tiny seeds and small seedlings can be a labor of love.
Set up the pots in the seed tray so each pot is level with the bottom of the tray. An extra tray may be needed if you notice any pots tilted at an angle.
Fill each pot with soil up to ¼- to ½-inch from the top edge of the pot. Place the tray on a flat, level surface under an artificial grow light or in a sunny window that receives at least 6 hours of direct light per day.
Plant two to three seeds into each pot at the depth recommended on the package. Follow the depth instructions carefully for each type of flower you are growing as some will require deep plantings and others barely need to be covered at all. Do not press the soil down to secure the seeds.
Pour an inch of water into the tray, avoiding the pots. This will allow the soil in the pots to draw the water up to the seeds without packing in the seeds, trapping them in the soil. Add more water, if necessary, to ensure the soil at the top of the pots is moist, but not soaking wet.
Place the clear, plastic lid of the tray over the top of the pots to seal in the moisture in the air and encourage the seeds to sprout. As the seeds grow into seedlings and reach toward the top, you can prop one side of the lid up with Popsicle sticks or pencils to allow for more aeration.
Continue to monitor the flower seedlings and add more water as needed when the soil appears dry. Depending on the type of flowers you are growing, seedlings are generally ready to be transplanted outdoors or into a container after two to three months.
